SHIELDING BOX ANTENNA FOR APPLICATION IN WUSB FLASH DISK

摘要

A novel design of ultra-wideband (UWB) antenna for wireless USB (WUSB) flash disk is presented. The baseband module shielding box and the RF module shielding box, two necessary parts for a WUSB flash disk, are subtly used as the radiators, which means that no other radiators are needed for the antenna in our design. A shorting tube is used as the signal wire channel to connect the baseband module and the RF module, which also is a shorting wire of the antenna. A prototype is implemented and tested, which shows that an impedance bandwidth of 8.5 GHz (2.5-11.0 GHz) for VSWR less than 2.0:1 is obtained.
